I have a question about the lower water pump base gasket. Is this suppose to have gasket sealer on it (perfect seal) or equivalent? I installed new lower pump base seals and O-ring tightened studs after all assembly and pressurized to 10lbs. PSI. it is leaking through the base gasket, seems like the O-ring should seal and not allow hardly any pressure on the gasket area but maybe I am wrong?
